An error has occurred :-(

Usual error causes

You started the application from an IDE and you didn't run yarn start or yarn run webpack:build.

You had a network error while running yarn install. If you are behind a corporate proxy, it is likely that this error was caused by your proxy. Have a look at the OncoKB error logs, you will probably have the cause of the error.

You installed a Node.js version that doesn't work with OncoKB: please use an LTS (long-term support) version, as it's the only version we support.

Building the client side code again

If you want to go fast, run ./mvnw to build and run everything.

If you want to have more control, so you can debug your issue more easily, you should follow the following steps:

Install yarn dependencies with the command yarn install

Build the client with the command yarn run webpack:build or yarn start
